PIPE-VISE AND MOUNTING.

Specification of Letters Patent.

Patented lday 22, 1917.

Application filed July 22, 1916. Serial No. 110,674.

To all whom it may concern:

Be it known that I, LOUIS W. Jones, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Pipe- Vises and Mountings, of which the following is a specification.

My invention relates to a pipe vise, and to means for easily securing it, and similar articles, to a post or other convenient support.

Referring to the drawings, in which the preferred embodiment of my invention is illustrated,-

Figure 1 is a side elevation of a pipe vise and its support;

Fig. 2 is a front elevation;

Fig. 3 is a vertical sectional view taken on the line III-III of Fig. 2;

Fig. t is a rear elevation illustrating the clamping means for securing the vise to a wooden post;

Fig. 5 is a side elevation of the vise and means employed for supporting it upon a metal pipe or column;

Fig. 6 is an elevation of a different embodiment of the vise-securing, post-clamping, means for temporarily holding the vise in working position;

Fig. 7 is a transverse sectional view taken on the line VIIVII of Fig. 6; and Fig. 8 is a transverse sectional view on the line VIIIVIII of Fig. 5.

The vise comprises a frame, 2, having near its opposite ends bearings, 3, adapted to rest against one of the faces of a post or stud, A, and serving to hold the frame somewhat off-set therefrom. The bearings, 3, may be perforated to receive screws for permanently attaching the vise when it is desired thus to mount it; but my invention, so far as it relates to supporting the vise, has to do with means by which it may be quickly and temporarily supported. a

In the frame, 2, are mounted a pair of serrated jaws 4 adapted to grip a pipe, B, that is held against them by a chain, 5, as is usual in pipe Vises. The jaws are easily removable, and are bolted to a supporting block, 6, that is so mounted in the frame that it may be easily removed when desired. The block is provided near one end with a hook, 7, adapted to enter a recess, 8, formed in the frame to receive it. The hook extends in the direction of the strain upon the chain, 5, when the latter is tightened to hold a piece of pipe in place. In order to more securely hold the block, 6, and prevent it from moving transversely its rear or inner edge is preferably seated in a groove, 9, formed in the frame, in which it may be and preferably is secured by bolt or screw, 10, although the use of this securing screw is not essential. The block is formed with a pair of abutments' or projections, l1, 12, with which the chain, 5, is adapted to be engaged. One abutment is in advance of the other, along the line taken by the chain when in use, and the distance between them is slightly different from the distance between the pivotal joints of the chain, the preferred arrangement being one in which the distance between the abutments is about half again the distance between the pintles, 13, uniting the chain links. These pintles preferably extend laterally beyond the side bars of the chain vso asto engage the abutments, which are slotted as represented at 14, to permit the chain links to enter the slots and lie between the separated sections of the abutments, with which the projecting ends of the pintles may then securely engage. One end of the chain is secured fast to a lever, 15, supported in the frame and upon which bears the cam or eccentric portion, 16, of the operating lever, 17. A

spring, 18, bearing upon the cam lever may be used to throw off from the lever, 15, if desired.

19 represents an adjusting screw having bearing in the frame and connected with the pivoted end of the lever, 15, in such ananner that by means of it the distance between such lever and the eccentric portion of the operating lever, may be varied. The exposed head of the screw is directly below the handle, 17, of the operating lever so that the person using the vise may, with the same hand that manipulates the handle, and without releasing his hold thereupon, adjust the screw as may be necessary.

In using the vise the pipe to be held is placed against the jaws, 4, and the chain, 5, is carried around it, and its free end dropped into the slotted portion, 14, of the block adjacent to the abutments, 11 and 12. The chain is drawn as tight as the user of the vlse thinks expedient, and a cross pintle, 13, is made to engage with one of the abutments, llor 12. The cam lever, 17, is then operated, and the movement of the lever, 15, takes up the slack in the chain, drawing it tightly against the pipe and the latter into engagement with the holding jaws, 4:, of the vise. If it be found that the chain is either too slack or too tight a short adjustment thereof, amounting to half the length of a link, can be effected by shifting the free end of the chain so that the pintlc is caused to engage with the other abutment than that just engaged. This adjustment in most cases will be found su'llicient, but if the chain be still either too slack or too tight upon the operating lever being thrown into locking position, then the fine adjustment necessary is effected by means of the screw 19. The location of this screw, as has been pointed out, is such that it can be easily reached by the workman without necessitating his release of the handle 17.

In order to secure the vise quickly and temporarily to the post A, or similar support, I employ clamping means consisting of a chain, 21, secured at one end, 20, to the frame, 2, and having its opposite or free end adapted to engage with a hook, 22, on the side of the frame opposite the attachment at 20. The chain passes around the post, A, and carries a clamp, 28. This clamp is in the form of a lever frame having a bearing portion, 2%, at one end adapted to rest against the face of the post and serve as the fulcrum of the frame. The chain passes through an intermediate tubular portion, 23, of the frame, while in the endof the frame opposite the bearing, 24:, is mounted a cam lever, 25, through which power is applied by which the vise is clamped and securely held in place upon the post. The frame, 28, is thus a lever of the second order, the fulcrum being the bearing, 24, the point of load connection being the intermediate tubular portion through which the chain, 21, passes, and the point of power application being the pivot, 27, uniting the cam lever with the frame.

The means thus far described and illustrated in Figs. 1 to f are particularly adapted for supporting the vise upon a wooden post rectangular in cross section. It is often, however, desirable to support the vise upon a cylindrical support such as a' metal pipe or column, and in Figs. 4, 5 and 8 I have represented means for permitting this.

Referring to these views 29, 29 indicate separable serrated bearings adapted to be easily applied to the portions 3 of the vise frame and to straddle, to a greater or less degree, and have good' gripping engagement with a pipe or cylindrical metal body. When the vise is to be supported upon a metal column or pipe the separable bearing pipe or column. used to hold the vise upon a cylindrical pieces, 29, are secured to the vise and their serrated portions made to engage with the The clamp, 28, that 1s metal support is like that represented in Figs. 1 and 4-, except that its bearing end, 24:, is serrated and adapted to straddle and engage with a cylindrical metal body. A. workman carrying the vise will usually have a pair of clamps, 28, 28, and a set of the separable pipe-engaging pieces, 29, having which he is equipped to temporarily support the rise to practically any object that he is likely to meet with under condilions where such tools are used.

In Figs. 6 and 7 l have illustrated a diffcrent form of clamp from that shown in Figs. 1, f and 5. In these views indicates the base piece of the clamp frame that is adapted to rest against the support to which the vise is to be temporarily secured. From this base piece rises an arch, 31, the crown of which is perforated and formed with a flat face as indicated at 32. 33 indicates the tubular portion of the clamp through which passes the chain, 21, that is attached to the vise and encircles the support, whether post or column. This tube is provided centrally with a screwthreadedstem, 3 1, which passes through the perforation in the crown, 32, in the arch of the frame. A nut, 35, engages with the screw-threaded stem and bears against the crown of the arch and serves as the means for moving the tubular part, 38, toward or from the support for adjusting the tension of the chain, 21. For some classes of work this form of clamp is to be preferred to that shown in the other views.

26 indicates a separable bracket or rest adapted to be readily applied to some convenient part of the clamping frame, and arranged to serve as a support for an oil can or other object that may be used in connection with a vise and which it is desired shall be supported conveniently relative thereto.

In using the apparatus described a workman will, if the support A be a wooden post first drive a nail, a, thereinto and hang the frame of the vise thereon. lhe chain, 21, is then passed through the tubular portion, 23 or 33, of the clamp, which is caused to engage the side of the post opposite the .vise, and the free end of the chain is carried around the post and drawn as tightly as can be done by hand, and made to engage with the hook, 22. The means employed for moving the tubular portion of the clamp through which the chain passes are then operated to put the desired tension on the chain for clamping the vise in place. These operations take but a .very short time, and when completed the vise is in position to be operated, as has been already set forth. When the work at hand has been performed the clamp is released, the chain, 21, unhooked, the clamp separated from the support, and the vise taken down. It will thus be seen that the parts described, the vise proper and its mounting, may be easily and quickly set up and taken down, and may be conveniently carried from place to place, thus remoying the temptation for a workman to leave his vise set up and exposed to theft when he quits his job for the day.

What I claim is:

1. A pipe vise comprising a frame, a separable supporting block carrying pipe jaws mounted in the frame, and provided with an abutment, a chain adapted to encircle the pipe and hold it clamped against the jaws, and the free end of which is adapted to be made to engage with the said abutment, and means for applying stress to the end of the chain opposite that engaging the abutment.

2. A pi e vise comprising a frame having a groovec face, a separable block carrying pipe-engaging jaws seated in the said groove in the frame, the block being arranged to hook over the end of the frame, and being provided with an abutment, a chain for encircling the pipe and holding it against the jaws, the free end of which is adapted to be brought into engagement with the said abutment, and means for applying stress to the chain to cause it to clamp the pipe.

3. A pipe vise comprising jaws adapted to engage with the pipe, a chain arranged to encircle the pipe and hold it against the jaws, a lever connected with one end of the chain, means bearing upon the lever to put stress upon the chain, and an adjusting screw for moving the fulcrum of the lever relative to the said stress-applying means.
